Django框架用户注销功能实现方法分析-创新互联

本文实例讲述了Django框架用户注销功能实现方法。分享给大家供大家参考，具体如下：

HttpResponse()里有个delete_cookie()方法专门用来删除cookie

我们到此来完整的实现一下：访问首页如果没有登录，就跳转到登录页面，登录成功之后再跳转回来的过程。

3个方法，index、login、logout

# coding:utf-8
from django.shortcuts import render,render_to_response
# Create your views here.
from django.http import HttpResponse
from UserClass import UserLogin
def index(request):
  msg = {'username':'guest'}
  if request.COOKIES.get('userlogin_username') != None :
    msg['username'] = request.COOKIES.get('userlogin_username')
  myReponse = render_to_response("index.html",msg)
  return myReponse
def login(request):
  msg = {'result': ''}
  if request.method == 'POST':
    getUserName = request.POST.get('username')
    getPwd = request.POST.get('pwd')
    # 实例化UserLogin类
    loginObj = UserLogin(getUserName,getPwd)
    if loginObj.isLogin():
      myReponse = HttpResponse("")
      myReponse.set_cookie('userlogin_username',getUserName,3600)
      return myReponse
    else:
      msg['result'] = '用户名或密码错误'
  myReponse = render_to_response("login.html", msg)
  return myReponse
# 用户注销
def logout(request):
  r = HttpResponse()
  r.delete_cookie('userlogin_username')
  r.write("")
  return r
